Large-flag construction: Sizes 8' × 12' and larger are finished with heavy rope and thimbles rather than standard grommets to provide a more substantial attachment system for large flagpole installations.

Choosing the Right Size

A 3' × 5' flag is a common residential size, but the correct flag depends on your flagpole height, mounting configuration, available clearance, and local wind conditions. Larger commercial flagpoles may require substantially larger flags and heavier attachment hardware.

Before ordering, confirm the dimensions and attachment method of your selected size and make sure the flag has enough clearance to fly without repeatedly striking nearby structures or landscaping.

Heavy-Duty Polyester Thin Blue Line American Flag

This flag is constructed from 2-ply Hi-Wind polyester, a heavier flag fabric designed for durability in outdoor conditions. The material provides a substantial feel while helping the flag withstand repeated exposure to wind and weather.

Details such as dense embroidered stars, sewn stripes, color-matched thread, reinforced hems, and four rows of lock stitching at the fly end provide a more durable construction than lightweight printed flags.

U.S. Manufacturing and Material Sourcing

This flag has been verified as made in the USA. Manufacturing origin does not automatically establish the origin of every raw fiber or accessory. Read the Federal Trade Commission's Made in USA guidance for details.

Flag Care and Display

• Inspect flag fabric, stitching and mounting points for wear; observe the manufacturer's guidance and the rated limits of poles and brackets.
• Avoid repeated fabric contact with buildings, branches or other obstructions.
• Follow the maker's fabric-specific cleaning and drying instructions, and dry the flag fully before storage.
